Using the proper tools and products is the right way to do things. I have this tutorial on my SCREEN PRINTING FORUM but will share it with you now. Hope this helps.

Step 1..
Place screen in washout booth and get wet on both sides. Then apply about 4-6 squirts from a spray bottle of an ink degrader. **DO NOT USE MINERAL SPIRITS**

Step 2..
Then scrub well with a brush, there are special brushes used here that will work well and only cost a few bucks. Then after the ink has broken down to a watery solution you can spray off. A power sprayer works best.

Step 3..
Then apply about 6-8 squirts of stencil remover on both sides. Aslo known as emuslion remover. Let it sit for a moment, then scrub with another brush that does not have any ink residue on it. You do not need to scrub very hard just let the chemical do the work.

Step 4..
Then power spray out the emulsion, in this case a hand sprayer will work because the chemical is the correct one and it will completly disolve the emulsion. But a power sprayer works best.

Step 5..
Here we see whats called a haze, the faint image left behind from the inks pigment. This screen will require a small amount of haze remover. You just spray on and scrub with a clean brush lightly to evenly apply the chemical. Let sit for about 5-10 min, then power spray out. At this point you should also degrease the screen, but some haze removers rinse very clean and do not require it.

Let the screen dry in a clean room and your done. You should allow the screen to dry overnight so that any water that has been absorbed into the mesh will evaporate. Not doing so may cause the emulsion to get bubbles or not bond to the mesh and will lead to other exposure issues and so on. Hope this helps.
